Definitions
- the invention relates to a counter-mandrel coupling element, a mandrel coupling element and a coupling system for a closed fluid transfer system.
- CMR drugs which are used in cancer therapy for example and which are primarily aimed at damaging growth-intensive tumor cells when used therapeutically, have a considerable potential risk outside of the actual therapeutic application . Due to their mechanism of action, such substances are in part self-carcinogenic, which is why contact with people who are not in therapy should be avoided. For CMR drugs, therefore, more and more closed ones are used in the manufacture of ready-to-use preparations
- CSTDs Solid System Transfer Devices
- An important component of such CSTDs are coupling systems that enable the safe transfer of CMR drugs or other substances and after disconnecting the connection, lock them dry in order to protect the environment from contamination, e.g. through leaks or the formation of drops on the surfaces of the coupling elements.
- Coupling systems of this type are generally associated with the terms “dry connection”, “automatic self-sealing technology” or “closed connection” and are essential for realizing closed fluid transfer systems.
- a known coupling system comprises a counter-mandrel coupling element and a mandrel coupling element, in which, in a coupling state, a mandrel of the mandrel Coupling element moves a counter-mandrel of a counter-mandrel coupling element against a spring force into a counter-mandrel receptacle, so that the openings of the mandrel protrude into the counter-mandrel receptacle and together with the counter-mandrel form a fluid channel that runs through the counter-mandrel receptacle.
- the disadvantage here is that the metal spring located in the counter-mandrel receptacle, which closes the counter-mandrel receptacle in the decoupled state via the counter-mandrel, is in contact with the fluid flowing through the fluid channel in the coupled state.
- the fluid channel formed has a high priming and residual volume due to the counter-mandrel receptacle containing the counter-mandrel and the spring.
- recessed components of the coupling elements or depressions formed by them are difficult to access for disinfection.
- the object of the present invention is to provide a counter-mandrel coupling element, a mandrel coupling element and a coupling system for a closed fluid transfer system through which a fluid channel with reduced priming and residual volume and a contact between metallic components and the fluid can be reduced.
- the object of the invention is achieved by a counter-mandrel coupling element for a closed fluid transfer system according to claim 1, a mandrel coupling element for a closed fluid transfer system according to claim 12 and a coupling system for a closed fluid transfer system according to claim 15. Further advantageous refinements of the invention emerge from the subclaims.
- the counter-mandrel coupling element for a closed fluid transfer system for receiving a mandrel of a mandrel coupling element for fluid exchange comprises a mandrel receiving section with a receiving opening that can be closed via a counter-mandrel guided in a counter-mandrel receptacle, the mandrel receiving section having at least one fluid opening in the area of the receiving opening.
- fluid can be exchanged via at least one fluid channel between an outer wall of the counter-mandrel receptacle and an inner wall of the counter-mandrel coupling element facing the outer wall of the counter-mandrel receptacle via the at least one fluid opening, the counter-mandrel sealing the counter-mandrel receptacle against the ingress of a fluid in the coupling state.
- the fluid exchange therefore does not take place via the interior of the counter-mandrel receptacle, since this is sealed by the counter-mandrel. Rather, an area which is formed between an outer wall of the counter-mandrel receptacle and an inner wall of the counter-mandrel coupling element opposite this wall is used as the fluid channel, which is via the fluid opening of the
- Mandrel receiving portion is accessible.
- the accessibility is created by the fact that the counter-mandrel is moved in a coupling state into a position in which it no longer closes the fluid opening in the area of the receiving opening of the mandrel receiving section, ie only after the mandrel of the mandrel coupling element has been inserted into the mandrel receiving section, a fluid connection between the Fluid channel and a mandrel opening of the mandrel of the mandrel coupling element allows.
- the counter mandrel is preferably moved into this position corresponding to the coupling state via the mandrel of the mandrel coupling element.
- other components of the mandrel coupling element can also change the position of the counter mandrel.
- a movement can also be initiated indirectly via intermediate elements.
- the formation of the fluid channel between an outer wall of the counter-mandrel receptacle and an inner wall of the counter-mandrel coupling element facing it can have almost any configuration with regard to the volume that can be formed.
- volume characteristics of the fluid channel largely independent of the installation space of other functional components.
- the volume of a fluid channel guided through the counter-mandrel receptacle cannot be taken into account Space for the elements of the counter mandrel guide, such as the metal spring, and the counter mandrel itself can be selected.
- the greatest possible independence of the fluid channel volume through the fluid channel according to the invention is only limited to the extent that it has to bridge at least the distance between the fluid opening in the region of the receiving opening and one end of the fluid channel.
- An outer wall of the counter-mandrel receptacle can be through the outermost outer wall of the counter-mandrel receptacle or an outer wall set back in the direction of the opposite inner side of the counter-mandrel coupling element, such as a groove base. In this way, different fluid channels can be formed in a simple manner by exchanging counter-mandrel receptacles with different contouring.
- the at least one fluid opening is preferably arranged radially with respect to an axis running through the receiving opening.
- An axis running through the receiving opening is an axis that lies within the receiving opening, that is to say does not intersect it.
- the axis passing through the receiving opening can also be brought into connection with the longitudinal axis of the receiving opening, although the two axes need not be identical.
- the axis running through the receiving opening can also have an angle of attack with respect to the longitudinal axis.
- the mandrel receptacle Due to the radial arrangement of the fluid opening, the mandrel receptacle can be continuously sealed off during the coupling process, since this continues until the opening of the Fluid opening accommodates both the counter mandrel and the dome with appropriate dimensioning.
- the mandrel receiving section is formed in the region of the receiving opening by means of a sealing element, in particular by means of a sealing element made of an elastomer.
- the sealing element enables a fluid-tight movement of the counter-mandrel and of the mandrel to be received in the mandrel receiving section. Due to the elastic design of the sealing element, it can adapt to differences in shape that can occur due to production. Elastomers provide corresponding properties with good and inexpensive availability.
- the mandrel receiving section forms the receiving opening by means of at least one exchangeable receiving element.
- an exchangeable receiving element Compared to an integral design with the counter-mandrel receptacle and / or the housing of the counter-mandrel coupling element, an exchangeable receiving element has the advantage that the receiving element can be changed and / or exchanged flexibly. This relates in particular to an exchange requirement in the case of changed designs of counter-mandrel and / or mandrel, as well as the replacement of faulty mandrel receiving sections in the area of the receiving opening or corresponding receiving elements.
- the receiving opening can also be formed by a plurality of receiving elements, such as an upper and lower receiving ring for forming an annular fluid opening.
- the fluid channel preferably runs linearly between the outer wall of the counter-mandrel receptacle and the inner wall of the counter-mandrel coupling element facing the outer wall of the counter-mandrel receptacle.
- the fluid channel thus has a predominantly smaller width than length in its connecting direction between the fluid opening and another end of the fluid channel with an opening for fluid exchange.
- the term “predominantly” can be due to a geometric configuration of the opening areas on both sides that deviates from the line shape. With a straight line shape of the fluid channel, the fluid to be exchanged is not subjected to any contour-related flow disturbances and can in particular be guided for fluid exchange over the shortest path between the fluid opening and the opening at the other end.
- the fluid channel runs at least in sections in an annular manner between the outer wall of the counter-dome receptacle and the inner wall of the counter-mandrel coupling element facing the outer wall of the counter-mandrel receptacle.
- the fluid channel thus runs over its full circumference at least in sections in relation to a counter-mandrel guide direction, around which a circumference of the counter-mandrel receptacle is formed in the radial direction over the length of the counter-mandrel guide.
- the fluid channel preferably runs in a ring shape over the entire area in which the outer wall and the inner wall facing the outer wall lie opposite one another, in order to utilize this advantage to the greatest possible extent.
- the mandrel receiving section preferably has a plurality of fluid openings in the area of the receiving opening, which are distributed at regular intervals at least along the circumference of the receiving opening.
- the mandrel to be received can have corresponding, in particular lateral, mandrel openings for this purpose, so that each fluid opening can be assigned to a mandrel opening.
- the fluid openings open into a fluid channel or several fluid channels.
- the number of fluid openings can also be higher than the number of mandrel openings. The higher the number of fluid openings, the greater the likelihood that a mandrel opening is positioned in the coupling state in such a way that it is in fluid connection with a fluid opening and thus with the fluid channel.
- the mandrel receiving section has, in the region of the receiving opening, a fluid opening which is configured in the form of a ring along the receiving opening circumference.
- a mandrel opening can thus be positioned as desired in the circumferential direction of the receiving opening at the level of the fluid opening or at a level for fluid exchange via the receiving opening.
- the mandrel receiving section has a plurality of fluid openings in the region of the receiving opening, which are distributed at predetermined intervals in at least one axial direction of the receiving opening.
- the counter-mandrel coupling element preferably comprises a positioning element in order to enable a defined positioning of at least one mandrel opening of the mandrel of the mandrel coupling element to be received opposite the at least one fluid opening of the mandrel receiving section in the area of the receiving opening.
- the counter-mandrel coupling element has a protruding guide section on its outer circumference, along which a mandrel
- Coupling element can only be moved to achieve a coupling state if it is brought into engagement with the guide section with a groove corresponding to the protruding guide section.
- the side of the counter-mandrel coupling element facing a mandrel coupling element for coupling can have a guide pin which is connected to a
- the counter-mandrel in the counter-mandrel receptacle can be moved into a closed position by a spring element, in particular a metal spring or an elastomer spring.
- the counter-mandrel By using spring elements that apply a spring force in the direction of the mandrel receiving section on the counter-mandrel, the counter-mandrel is constantly urged into the receiving opening. If no mandrel is moved into the mandrel receiving section, the counter mandrel thus automatically seals the receiving opening. If the spring force is overcome by inserting a mandrel, the counter mandrel is indeed moved against the spring force, but remains in a contact position with the element initiating the movement.
- Metal springs offer far-reaching advantages due to their high availability and material-related stability properties that are constant over a wide range. Elastomer springs are also readily available and flexible in their geometrical design. Depending on the load scheme and environmental conditions, elastomer springs also offer weight advantages over metal springs. In addition, can if contact with a fluid cannot be ruled out, a spring active substance with a lower tendency to react with the fluid can be selected.
- the invention is also directed to a mandrel coupling element for a closed fluid transfer system for introducing a mandrel for fluid exchange into a counter-mandrel coupling element, as described above, the mandrel having at least one lateral mandrel opening for fluid exchange.
- the mandrel can be brought into a coupling state through the at least one lateral mandrel opening with at least one fluid opening of the mandrel receiving portion in overlap or at least in a fluid connection.
- the mandrel preferably has a plurality of mandrel openings in the circumferential and / or axial direction.
- fluid channels can thus be controllable or at least an overlap probability can be increased.
- compatibility with differently configured mandrel receiving sections is also increased, in particular with regard to the positioning of the fluid openings on the mandrel receiving section and / or their dimensioning.
- the at least one mandrel opening is essentially annular in the circumferential direction.
- the term “essentially” refers to the fact that the mandrel area facing the counter mandrel in the coupling state requires a connection to the mandrel in order to form a delimitation of the annular formation of the mandrel opening.
- the connection can be implemented, for example, via an internal connection structure and / or external connection webs of the dome. Outer connecting webs interrupt the ring shape of the mandrel opening, but without significantly impairing the functionality of the ring shape.
- the ring shape reduces the requirements for positioning accuracy.
- a larger opening area can be provided for fluid exchange.
- the invention is also directed to a coupling system for a closed fluid transfer system which comprises a counter-mandrel coupling element according to the invention and a mandrel coupling element according to the invention.

- Figure 1 shows the cross-sectional view of a counter-mandrel coupling element 100 in a sectional plane parallel to the longitudinal axis of the counter-mandrel coupling element 100.
- the counter-mandrel coupling element 100 comprises a counter-mandrel receptacle 11 for receiving a counter-mandrel 10, which is guided in the counter-mandrel receptacle 11 via a spring element 19.
- the inner wall of the counter-mandrel receptacle 11 together with the spring element 18 forms a counter-mandrel guide.
- the counter mandrel holder 11 also has a
- the sealing element 18 here has two fluid openings 14 extending radially to the longitudinal axis, through which a fluid connection to a fluid channel 15 can be created.
- the sealing element 18 forms a stop for counter-mandrel 10, so that its movement path in the counter-mandrel receptacle is limited.
- the counter-mandrel 10 has a flange which is supported against the sealing element 18 in a position in which the fluid openings 14 formed by the sealing element 18 are closed by the counter-mandrel 10.
- the side of the counter-mandrel 10 facing away from the spring element 19 closes flush with the side of the sealing element 18 facing away from the spring element 19, so that disinfection is facilitated by the flush surface.
- the side of the counter-mandrel 10 facing away from the spring element 19 is also shaped in a concave manner. A centering function is supported when a complementary, in this case correspondingly convex, shaped dome 30 (FIG. 2) is received.
- the fluid openings 14 are opened after a certain movement path or at least no longer closed by the counter mandrel 10.
- a fluid connection to the fluid channel 15 can be created, which extends between an outer wall 16 of the counter-mandrel receptacle 11 and an inner wall 17 of the counter-mandrel coupling element 100 opposite the outer wall 16, for example an inner wall of the housing.
- the fluid channel 15 connects the fluid openings 14, which here extend through the sealing element 18 via the counter-mandrel receptacle 11 in the area of the mandrel receptacle section 12 to the fluid channel 15, with an opening 20 at another end of the fluid channel 15 for fluid exchange, here an outlet opening, which likewise can be used as an inlet opening.
- the fluid channel 15 divides in a flow direction from the opening 20 in the direction of the fluid openings 14 into two straight, linear fluid channel branches, each of which is in fluid connection with a fluid opening 14.
- the counter-mandrel receptacle 11 is not formed integrally with the housing of the counter-mandrel coupling element 100, but is inserted into the housing as a separate component, in particular screwed, clamped, glued or otherwise connected to the housing in a stable position.
- a reversibly releasable connection is preferably to be provided for exchanging the counter-mandrel holder 11.
- the sealing element 18 is designed as a separate, exchangeable element made of an elastomer, which is inserted into the mandrel receiving section 12 of the counter mandrel receptacle 11.
- the counter-mandrel coupling element has on its outer circumference a fastening section 21 into which the fastening element 35 of a mandrel coupling element 200 (FIG. 2) can engage in order to Coupling element 100 and the mandrel coupling element 200 to be connected to one another in a stable position in a coupling state.
- the fastening section 21 and the fastening element 35 together form a snap connection.
- other fastening mechanisms can also be used, such as screw connections.
- the mandrel coupling element 200 comprises a mandrel 30 which is surrounded by a housing 34 and has two lateral mandrel openings 31.
- the mandrel 30 is surrounded by a sealing element 32 that is movably guided along the mandrel 30 via a spring element 33.
- the sealing element 32 is here on a side facing the mandrel 30 by a ring element made of an elastomer and on the side facing away from the mandrel the Ring element receiving dimensionally stable sleeve for engagement with the spring element 33 is formed.
- the spring force of the spring element 33 urges the sealing element 32 in the direction of the mandrel tip into a position that is determined, for example, by an end stop.
- the housing 34 of the mandrel coupling element 30 also has an annular inwardly extending fastening element 35 in order to engage a fastening section 21 of the counter-mandrel coupling element 100 in a coupling state with a counter-mandrel coupling element 100.
- the coupling system 300 shown in a coupling state in FIG. 3 the functioning of the counter-mandrel coupling element 100 according to FIG. 1 and the mandrel coupling element 200 according to FIG. 2 is described again below. To simplify the description, it is assumed that this is only the mandrel coupling element 200 is moved in the direction of the counter-mandrel coupling element 100, it also being possible in practice for both coupling elements to be moved towards one another.
- the coupling system 300 is not yet in the coupling state shown in FIG. 3 and both coupling elements have the basic state shown in FIGS.
- the sealing elements 18 and 32 are also in contact with one another.
- the mandrel coupling element 200 If the mandrel coupling element 200 is now moved further in the direction of the counter-mandrel coupling element, the mandrel 30 pushes the counter-mandrel 10 against the spring force of the spring element 19 into the counter-mandrel receptacle 11.
- the sealing element 32 is moved along the dome 30 into the housing 34 via the sealing element 18 and the mandrel receiving section 12 in a direction opposite to the spring force of the spring element 33.
- the spring force of the spring element 33 exerts a surface pressure on the contact surface between the sealing element 18 and the sealing element 32, which allows a further seal.
- the mandrel 30 or the mandrel coupling element 200 is now moved further in the direction of the counter-mandrel coupling element 100 until the fastening element 35 of the mandrel coupling element 200 engages in the fastening section 21 of the counter-mandrel coupling element 100.
- the coupling state is thus achieved in which the mandrel 30 projects so far into the receiving opening of the mandrel receiving section 12 that the lateral mandrel openings 31 are opposite the fluid openings 14.
- an exchange of fluid can take place along the flow path through the fluid channel 15, shown in dotted lines in FIG.
- the connection between the counter-mandrel coupling element 100 and the mandrel coupling element 200 is fluid-tight.
- the mandrel openings 31 thus do not come into contact with the environment. Likewise, possible fluid residues in the area of the fluid openings 14 are wiped off via the counter mandrel 10.
- the variant shown in FIG. 4 in a decoupled state of the counter-mandrel coupling element 100 and the mandrel coupling element 200 differs in the spring elements 190 and 330.
- the spring element 190 of the counter-mandrel coupling element 100 is designed here as an elastomer spring which is pressed against the counter-mandrel 10 and that side of the counter-mandrel receptacle 11 facing away from the mandrel receiving section 12 is supported.
- the spring element 330 of the mandrel coupling element 100 is also designed as an elastomer spring.
- the spring element 330 comprises a sealing section 331, which fulfills the function of the sealing element 32 shown above, so that the sealing element 32 and the spring element 32 shown above are formed in one piece via the spring element 330.
- the fastening sections 21 can be designed differently.
- the fastening section 21 according to FIG. 5 can only be configured in sections via a projection on the outer surface of the counter-mandrel coupling element 100 or according to FIG. 6 as a circumferential groove.
- FIG. 7 another variant is shown in Figure 7, in which a coupling system 300 'does not include a cylindrical counter-mandrel coupling element 100 and a cylindrical mandrel coupling element 200, but the counter-mandrel coupling element 100 ' and the mandrel coupling element 200 ' each for engagement between the fastening element 35 and the fastening section 21 comprise flat outer side sections, so the counter-mandrel coupling element 100 'in Figure 7 has two opposite flat counter-mandrel
- Coupling element housing sections 110 while correspondingly two flat mandrel coupling element housing sections 341 are provided on the side of the mandrel coupling element 200 ' .
- the counter-mandrel coupling element housing section 110 is flat on its outside, at least over the area from the mandrel receptacle to the fastening section 21 is, while the mandrel coupling element housing sections 341 is formed correspondingly flat at least on an inner side.
- the coupling elements 100 and 200 can also be coupled via a screw connection.
- the sealing element 32 does not have to be guided along the mandrel 30 via a spring element 33, but can itself be designed to be resilient, surrounding the mandrel up to a support surface opposite the mandrel tip.
